Yeah, and you probably got a 5/8" master and a 7/8" or 3/4" slave, which is the hydraulic equivalent of a longer clutch arm. The clutch effort is VERY light on my car, especially with the Sachs HD clutch instead of the Kennedy.
Weddle also makes a 16mm clutch cross shaft for a later style throwout bearing. They also stock various bushings to fit the trans case. They can get you parts to make just about any combo work. They even sell an adapter sleeve that allows later style clutches to work with early 6v transmissions.
